In the master’s thesis an open-source software package is designed and developed for calculating the maximum response and fatigue damage spectrum of deterministic and random excitation signals defined in the time and frequency domains. The software code results are validated in accordance with available literature. In the experimental part of the thesis, a vibration fatigue test of rectifier diodes was designed and conducted at two load levels. The fatigue parameters obtained in this way were used to evaluate different load profiles of rectifier diodes using the fatigue damage spectrum.
